Gary Eugene Holmes, 33, was arrested Thursday in the death of 3-year-old Acen King, Joshua Kaplan, a spokesman for the US Marshal's service, told the AP.

Holmes is being held on capital murder and committing a terroristic act charges.

Acen was Christmas shopping with his grandmother, Kim King-Macon, on Saturday when Holmes allegedly began honking at them because King-Macon "wasn’t moving fast enough at a stop sign,” the AP reported.
